Patented Aug. 25, 1953 UNITED STATES PATENT OFFICE A 2,650,1'79 METHOD or AND APPARATUS FOR WASHING MILKIN G MACHINES Austin E. Anderson, Jamestown, N. Y. Application May 8, 1948, Serial No. 25,947

Claims.

The foregoing and other objects will manifest themselves as this description progresses, reference being bad to the accompanying drawing wherein Fig. 1 is a view depicting the general layout of the system and showing the washing chambers in section; and

Fig. 2 is a fragmentary view of the flow directing and turbulence creating pulsator.

atmosphere. The operating pheric and for the purposes of this description subatmospheric pressure will be considered as the operating pressure. a

With the parts arranged as illustrated in Fig. 1 and the suction line connected to the chamber 2, the path of air and liquid flow will follow the arrows with the result pressure will displac the washing solution back into chamber I. This Washing solution transfer will continue back and forth at regular intervals throughout the pressure differential to shift the valve ing cam l1 whereby one compartment reversw ll be placed in communication with the source of suction for evacuating the air content of the companion washing chamber. Whenever this reversal takes place, the liquid content of the vented washing chamber will be displaced by the air pressure differential over into the companion chamber and as the displacement of a predetermined volume of the washing solution nears completion the atmospheric air will gurgle into the several teat cups and agitate the solution therein to cause a turbulent condition for swishing the solution through the milk passages. The result is that any adhering foreign particles will be shaken from the passage wall and carried along with the liquid stream over into the companion washing chamber. The duration of this period of turbulence will depend upon the' capacity of the pulsator compartments as well as the restriction afforded by the pulsator bleed passages. Furthermore, the turbulent action of the washing fluid will be increased by placement of the teat cups upon their sides in the bottom of the respective washing chambers.

The branch suction passages Hi may enter their respective chambers through fittings 19, the latter serving also as supports for the struts which are employed to hold the covers 3 in position, these struts comprising a sleeve section pivoted at 21 and having an extensible sec tion'ZZ threaded therein for reacting against the bail 3. The length of the strut being once obtained, may be secured by means of a jam nut 23. By reason of the location of the pivot M the strut may be swung laterally to disengage the bail, the'outer end of the strut being formed with a seat to receive the bail when in its operativeposition. The flow directing and turbulence creating pulsator l3 may be mounted on a suitable support 24 by a generally G-shaped bracket 25, the underside of the pulsator engaging in a seat where it is retained by a resilient spring detent 25.

The improved method and apparatus for washing the claw and cup assemblages is simple and yet effective in thoroughly cleansing the units, and while the foregoing description has been in detail it is without thought of limitation since the inventive thoughts disclosed are capable of assuming other physical embodiments without departing from the spirit of the invention and the scope of the appended claims.

What is claimed is:

1. vWashing apparatus for the claw and teat cup assemblages of a milking machine, comprising a pair of liquid containing chambers, closure means sealingand'giving accessito the same, a transfer passage connecting the two chambers and having its opposite ends connectible to respective claw and cup'assemblages in the chambers for opening into the latter through the milk passages of the cups, and a pulsator connected to the two chambers and acting first to connect one chamber to a source of operating pressure and the companion chamber to the atmosphere concurrently and then to reverse the connections to displace the liquid alternately from one chamber to the other through the milk passages of the claw and cup assemblages and the connecting transfer passage.

2. Washing apparatus for the claw and teat cup assemblage of a milking machine, comprising a pair of liquid containing chambers, closure means sealing and giving access to the same, a transfer passage connecting the two chambers through the closure means and terminating in each chamber with means for communicatively attaching a claw and cup assemblage thereto for fluid flow back and forth from one chamber through the assemblage therein and the transfer passage into the other chamber through the assemblage in the latter, means supplying air pressure to thechambers for effecting such displacement, and pressure responsive means operating to confine the air pressure to one chamber at a time while venting the companion chamber to the atmosphere.

3. Washing apparatus for the claw and teat cup assemblage of a milking machine, comprising a pair of liquid containing chambers, closure means sealing and giving access to the same, a transfer passage connecting the two chambers and terminating in each chamber with means for communicatively attaching a claw and cup assemblage thereto for fluid flow back and forth from one chamber through the assemblage therein and the transfer passage into the other chamber through the assemblage in the latter, a suction line, and pressure responsive means alter- 'nately acting to establishing communication between the suction line and the two chambers while venting thecompanion one of thechambers to the atmosphere.

4. A method of washing milking machine teat cups, consisting in placing the cups on their sides in a submerging volume of liquid within a chamber, then displacing the liquid from the chamber through the cups by a gas pressure until the liquid level falls sufiiciently to admit pressure gas into the cups along with the liquid for agitating the latter, andmaint'aining the gas pressure for a predetermined time interval to produce a prolonged period of turbulence within the cups.

5. A washing system for cleansing the milk passages of milking machine units, comprising plural containers, covers for the containers hav ing a pressure connection and a unit connection therethrough, a transfer passage joining the two unit connections, and' means connected to the pressure connections and operable to vent one container to the atmosphere while connecting the companion container to a source of operating pressure to displace a washing solution from one container to the other through the transfer passage and the terminally connected units, and pressure responsive means for reversing the pres suredifferential inthe two containers.
